How to Subtract Binary Numbers

1. Write down the two numbers you want to subtract in binary format.
2. If the second number is longer than the first, add zeros to the beginning of the first number to make them have the same number of digits.
3. Start from the rightmost bit and subtract each pair of bits starting from the right, just like you would with decimal subtraction.
4. If you need to borrow, borrow from the next bit to the left.
5. Continue this process until you have subtracted all the bits.
6. The final answer will be the result in binary form.

Subtracting binary numbers is similar to subtracting decimal numbers, but it involves working with bits (0s and 1s) instead of base-10 digits. Each bit in a binary number represents a power of 2, just like how each digit in a decimal number represents a power of 10.

Example:

Let's subtract 1011 from 1101 in binary:

1101

- 1011

----

010

In this example, we start from the rightmost bit and subtract 1 from 1, which gives us 0. Then, we subtract 1 from 0, and we need to borrow from the next bit. After borrowing, we get the final answer of 010.

Binary Subtraction Rules:

1. 0 - 0 = 0

2. 1 - 0 = 1

3. 1 - 1 = 0

If you need to borrow during subtraction, you borrow from the next higher bit, just like in decimal subtraction. Make sure to practice binary subtraction to become comfortable with the process.
